Abie, I think the idea of paying it forward should be implemented in almost any possible business model at the moment. Ideally, the concept could transition into a non-profit business model though I am more convinced ordinarily by the promising nature of Social Enterprises (which may be for-profit businesses that do good) rather than non-profit businesses (which may pay their CEOs and executive employees hefty salaries despite not taking profit).
I think this sounds awesome! Consider looking into UC Berkeley's Artificial Intelligence robot that helps complete minuscule tasks and learns new tasks. That would help moms incredibly if it were added on, in addition to the chat bot.
